I've purchased some SIMM chips to install in my Mac Plus, but I have a
Radius Accelerator installed. Before I open it up, I was wondering
if the presence of this board would make it difficult for a
non-handyperson like myself to do it.
Any help will be greatly appreciated.

It is not blocked, you must only take care of not ripping out the accelerator board when changing this SIMM from 256K to 1meg (necessary for a 1meg to 2.5 meg upgrade OR any upgrade to 4 megs). You will also need to cut a resistor on the board (it is labeled RAM SIZE) but it is not hidden and is easy to reach. This biggest problem you will encounter is extracting the motherboard and replacing it. This is done by prying the SIDES of the motherboard OUT of its holders with a screwdriver. Slight bending of the Mac chassis and motherboard are required! DO NOT TRY TO SLIDE IT OUT LIKE A NORMAL MOTHERBOARD, you will damage the accelerator. If you don't understand what I'm talking about, have a dealer do the upgrade (you can blame them if anything goes wrong :-) ). -- +----------------------------------------------------------------------------+ | Pascal Gosselin | Internet: Pascal@cam.org Applelink: CDA0585 | | Gest-Mac Inc.
